HOW THE "EBS" FILTERS WORK The EBS is an automatic filter, with a self-cleaning mechanism driven by an electric motor. The EBS is designed to work with various types of screens in filtration degrees from 800 to 10 micron, and is available in 8" to 24" inlet/outlet diameter. Filtering process: Raw water flows into the filter through the cylindrical filter element from the inside-out, causing particles to accumulate on the inside screen surface which causes the development of a ”filter cake”. The accumulation of the filter cake causes pressure differential to develop between the filter inlet and outlet. A pressure differential switch senses the pressure differential across the screen and when it reaches a preset value, the cleaning mechanism is operated.
Drive unit
Cleaning process: The EBS begins the self-cleaning process when the pressure differential across the screen reaches a preset value or an (adjustable) amount of time has passed. Cleaning of the filter's fine screen is carried out by the suction scanner which is a motor driven assembly that rotates while also moving linearly. It consists of a central tube with tubular nozzles equally spaced along the length of the central tube. An exhaust flush valve connects the internal cavity of the suction scanner to atmospheric pressure outside the filter body. By opening the exhaust valve, the differential pressure between the water inside the filter and the atmosphere outside the filter creates high suction forces at the openings of each of the suction scanner nozzles. This suction force causes water to flow backwards through a small area of screen in front of each nozzle, pulling the filter cake off the screen and sucking it into the suction scanner and out through the exhaust valve to waste. The driving mechanism rotates the suction scanner in a slow, controlled motion. The cleaning cycle is completed in approx. 30 seconds. During this time the nozzles cover 100% of the screen removing the filter cake from the entire screen surface. During the self-cleaning cycle, filtered water continues to flow downstream of the filter.

Weave Wire screen
The EBS filter is equipped with a pressure differential switch that transmits an electric signal to the electronic control board, which initiates the flush cycle. A solenoid operates the exhaust valve by means of a hydraulic command or compressed air. The filter operation and cleaning cycle are controlled and monitored by a Programmable Logic Control (PLC). The PLC allows maximum flexibility in control options and has many features that can be incorporated per the customer's needs.

The MegaEBS filter consists of four EBS screen elements and cleaning mechanisms within one housing. An integral control panel allows for sequential operation of the cleaning mechanisms, one-by-one, in pairs, or all four units simultaneously. The Mega EBS is an excellent solution for applications with space limitations or when a limited number of filter units are required. Inlet
